The UNT Libraries currently use the Library of Congress system of call numbers to classify most of the materials in our collections. Classification causes similar items to be together on the shelves.
Library of Congress call numbers use both letters of the alphabet and numbers.
For most fields, the letters in call numbers have nothing to do with the names of the topics in question. Music is one of very few exceptions.
Most of our print journals do not have call numbers. Instead, they are shelved in alphabetical order by journal title. There are a few exceptions, however. Annuals, or journals only published once a year, usually have call numbers. Thus, if you are searching for a journal by title on the shelf and cannot find it, look it up in the catalog. It may be one of the annuals, and you will need to look for it under its call number.
